Embodiment 1

[0028] Weigh the raw materials in the following proportions by weight: 43g of 3,3-ethyl dimethacrylate, (3beta,20beta)-3-hydroxyolean-12-en-29-acid 42g, 1-phenyl-2 -Pyrrolidone 21g, ethyl 3-benzylamino-2-butenoate 13g, glycine 34g, 1-methyl-1H-pyrrole-2,5-dione 10g, (E)-2-methyl-2-butan Isopropyl enoate 31g, 2-cis,4-trans-5-(1-hydroxy-4-oxo-2,6,6-trimethyl-2-cyclohexen-1-yl)- 15g of 3-methyl-2,4-pentadienoic acid, 55g of 17beta-hydroxy-17alpha-ethynyl-androst-4-en-3-one.

[0029] The preparation method of the insecticide for controlling rice water weevil in this example: add distilled water in proportion to the reaction pot, and when the temperature in the reaction pot rises to 65°C--80°C, add 3,3-dimethacrylate Esters, (3beta, 20beta)-3-hydroxyolean-12-ene-29-acid, 1-phenyl-2-pyrrolidone, and stirred for 1 hour, then cooled to 50 ° C, added 3-benzylamino- Ethyl 2-butenoate, glycine, 1-methyl-1H-pyrrole-2,5-dione, (E)-2-methyl-2-butenoic acid isopropyl ester, stir for 30 min...

Embodiment 2

[0031] Weigh the raw materials in the following proportions by weight: 45g of 3,3-ethyl dimethacrylate, (3beta,20beta)-3-hydroxyolean-12-en-29-acid 36g, 1-phenyl-2 -Pyrrolidone 25g, ethyl 3-benzylamino-2-butenoate 16g, glycine 28g, 1-methyl-1H-pyrrole-2,5-dione 14g, (E)-2-methyl-2-butan Isopropyl enoate 34g, 2-cis,4-trans-5-(1-hydroxy-4-oxo-2,6,6-trimethyl-2-cyclohexen-1-yl)- 9 g of 3-methyl-2,4-pentadienoic acid, 59 g of 17beta-hydroxy-17alpha-ethynyl-androst-4-en-3-one.

[0032] The preparation method of the insecticide for controlling rice water weevil in this embodiment is the same as that in Example 1.
